HAND-STAMP.

SPECIFICATION forming part of Letters Patent No. 308,309, dated November 18, 1884:.

Application filed June 25, Iss1. (No model.)

To all whom it may concern.-

Be it known that l, JosEPH P. ELLACOTT, a citizen of the United States, residing at Ohicago, in the county of Cook and State of lllinois, have invented certain new and useful Improvements in Hand Stamps, which are fully described in the following specification, reference being had to the accompanying drawings, in which- Figure 1 represents a side elevation of a hand stamp embodying my improvements; Fig. 2, an end View of the same; Fig. 3, a longitudinal section taken on the line mm of Fig. 2; Fig. 4, a detail plan view of the stampinghead inverted. Fig. 5 is a detailed and slightly-enlarged elevation of part of the side of the stamp-head opposite to that shown in Fig. 1, and illustrates the device for locking the die against rotary motion, the plate which covers the spring actuating the bolt 9 being broken Fig. 7 is an elevation of the opposite side of the stamp to that shown in Fig. 1.

The invention consistsin the particular devices and combinations of devices, which I will now proceed to describe, in their connection with the mechanism of a hand-stamp, and

which I will then point out by themselves in the claims.

In the drawings, A represents the frame of the hand-stamp; a, the shoes, of india-rubber or other similar material, sprung into dovetail sockets a, these sockets being largest in the upper part, and the shoes being broad enough to fill this upper part when not considerably compressed.

B is aseries of date-wheels, of ordinary con struction.

O is the ribbon-supplying roller; 0, the ribbon; c, a die of ordinary construction.

D is a spring-plate pivoted to the stampframe at d and to the stamping-head E at 6. By its use the ribbon 0 can be taken up by the automatic feeding mechanism, hereinafter specified, without any occurrence of material slackening on the return of the stamping-head. The plate D may with advantage be sheathed in a recessed portion, c of the frame A, as shown in the drawings, for the purpose of protecting the ribbon from dust and to guide it.

e and e" are guides, ande is the take-up roller, operated at each stroke of the stamping-head by the ratchet Fthrough the pawlf, driven by the lever f, having its fulcrum at its slotted end, where it ineloses the projecting end of the pin f which supports the spring of the stamping-head. I

f is a retaining-pawl, operated by a spring, f, which presses, by virtue of its tension. on a flattened side of the shaft of the pawl the flattening being on that side which is uppermost when the pawl engages with the ratchet F, so that the tension of the spring holds the pawl in place, The spring is arranged just back of the ratchet and pawl, as shown in Fig. 1.

G is the removable key-shaped die, which die is inserted through the key-hole-shaped slot 9 in one side of the stamping-head, which, among other functions, has those of a die-holder, the square end of said slot being for the admission of the bit or type; After insertion the die is turned, so as to bring the type into the position shown in Fig.3, thus locking said die, except that it may be turned back into the position in which it was inserted.

In combination with the locking device just described may be used the locking device described as follows: A bolt, 9, sliding in ways on the other side of the stamping-head, is by a suitable spring pressed endwise against the inner and reduced end of the die, thus preventing any accidental rotary motion thereof. This side of the reduced end of the die, which, when the die is in its normal position, is in contact with the spring-bolt g, is preferably flattened, as shown in Fig. 5. The inner and reduced end of the die is beveled conically, to provide for its passing during its insertion the spring-bolt g, which protrudes as far as permitted by the pin 9 'This pin projects laterally from the bolt and locks against the end of a slot cut in the side of the stamp-head parallel with the bolt, as shown in Fig. 5.

H is a gage, adjustable by means of slots and set-screws h inserted therein, and is designed to be used where the stamping is to be done at a uniform distance from the edge of thematerial to be stamped. I is a non-adjustable gage for the same purpose.

The above apparatus will be found especially useful in stamping coupon or local railroad tickets, in which case a separate upper die may i be provided for each terminal station, and the lower die may represent the selling-office.

I do not claim the feeding mechanism above described, consisting of a ratchet operated by a pawl in contact with a slotted lever pivoted on the stamp-head; nor do I claim the combination of the spring-plate D with the fixed base, vertically-reciprocating stamp-head, and ribbon-Winding drum; but

Vhat I do claim as my invention, and de sire to secure by Letters Patent, is

1. In a hand-stamp, a vertical]y-reciprocating stamp-head, a ribbon-winding roller arranged on the stamp-head, means for operating said roller by the stroke of the stamp-head, the fixed stamp-frame provided with the recessed portion cf, the arched spring-plate D, connecting the stamp-head with the stampframe, and arranged in the recessed portion a", and the ribbon borne at one end on the fixed stamp-frame and at the other on the windingroller, and arranged over the arch of the spring-plate, all constructed, arranged, and

operating in combination, substantially as described, for the purpose of guiding the ribbon and protecting it from dust.

2. The removable die 4}, having type proectlng from one of IlS 'SIdGS and flattened l 7 the farther side of the stamp-head horizontally and transversely to the die, all constructed, arranged, and operating in combination, substantiall y as described, for the purpose oi'locking the die against both longitudinal and rotary motion.
